Title: Laser processing
Inventor: SHINONAGA HIDEYUKI
IPC: B23K26/382
Filed: 1989-01-24
Abstract: PURPOSE:To obtain a shape having a prescribed size without having the surface chipped by burning by irradiating the through-hole formed by piercing with laser light along the side face of the hole. CONSTITUTION:After the through-hole 9 by piercing is formed, hole working of about 0.5mm is executed by, for example small circle working. The through- hole 9' is, therefore, formed by this working to have a larger hole diameter. The prescribed shape 6 is thereafter subjected to laser cutting with the through- hole 9' increased in size as the start point for laser cutting. The through-hole 9' is, therefore, expanded by the small hole working and the dross sticking thereto is chipped off simultaneously and is prevented from sticking to the rear. Continuous cutting along the working line 14 of the cutting is thus possible.

IPC: B01D37/04
Filed: 1980-02-06
Abstract: PURPOSE: To increase the rate of treatment per unit time and facilitate peeling of cake after filtration by supplying a slurry at a low rate in the initial period of filtration thence shifting to an ordinary rate of supply in filter pressing of the hard-to- filter slurry.  
     CONSTITUTION: In filter pressing of a slurry contg. cake of 1×10 12 m/kg in average resistance value under 1kg/cm 2  filter pressure and ≥0.6 in compression index such as excess sludge, digested sludge and the like in activated sludge treatment, the rate of supply of the slurry in the initial period of filtration is set at ≤0.02m/H. Under these conditions, ≥20wt% the amount of the slurry filtered in one time is filtered, after which the rate of supply is increased successively or stepwise up to an ordinary rate of supply. When the predetermined rate of supply can no longer be maintained, one time of the filtration ends at that time. According to this method, the clogging of the filter cloth surface is prevented and the efficiency of filtration is improved.

Title: Surface heater
Inventor: ASAI YASUHIRO
IPC: H05B3/20
Filed: 1997-01-28
Abstract: PROBLEM TO BE SOLVED: To provide a surface heater, of which power consumption can be reduced and which can efficiently generate heat at a low voltage, by forming a surface heater of steel or stainless steel or brass into a thin tape. SOLUTION: A surface heater 1 is made of steel, or stainless steel or brass, and formed into a thin tape shape having width at 10mm and thickness at 0.3mm. Since cross sectional area, which determines resistance value for controlling heating, is formed thin, it can efficiently generate heat at a low voltage. With a rise of heating temperature, current value is lowered so as to contribute to the power saving. Since natural resistance value of these material is low, high current flows and heat is generated more quickly than the known nichrome wire. Voltage can be changed by adjusting the tape length L. Namely, this heater can be used at a low voltage such as 50V or less by shortening the length L, and it can be used at a general voltage such as 100V, 200V by prolonging the length L.
